Description or summary of the book: Telegraph letter writers, that most astute body of political commentators, are probably not alone in thinking that politics has taken some strange turns in recent years. The first coalition government since 1945 has led the country from the subprime to the ridiculous, lumbering from Leveson to Libya, riots to referendums, pasty-gate to pleb-gate, Brooks to Bercow, the Bullingdon Club to the Big Society.Five years is a long time in politics. Fortunately for us, it has also been a most fertile period for the Telegraph's legion of witty and erudite letter writers, who have their own therapeutic way of dealing with the pain. An institution in their own right, theirs is a welcome voice of sanity in a world in which the lunatics appear finally to have taken over the asylum.
